PRODUCT DESCRIPTION
Machine vibration velocity sensor
Bently Nevada 107770-03-03 is a velocity transducer. It converts vibration at the mounting surface into a velocity signal for the receiving instrument. Correct mechanical coupling and a compatible input are essential; the application must remain within the documented frequency response and environmental limits of the supplied configuration.
This assembled order combines a 330500 sensor with the 21128 housing, a one-half-inch NPT mounting interface and the selected conduit outlet. Confirm the complete approved installation, including the required cable, before treating it as an interchangeable sensor assembly.

MACHINE VIBRATION VELOCITY SENSOR
Integrating 107770-03-03
It converts vibration at the mounting surface into a velocity signal for the receiving instrument. Correct mechanical coupling and a compatible input are essential; the application must remain within the documented frequency response and environmental limits of the supplied configuration.
Select a receiver input compatible with the specified velocity sensitivity, bias and excitation arrangement. Do not substitute a self-generating moving-coil sensor solely because both devices measure velocity. The 21128 housing requires the documented 89477 cable; 84661 is not its approved cable substitute.
Use the documented mounting interface and torque where specified. Secure the cable and confirm the input polarity, excitation and operating range before energizing. For high-temperature systems, keep the electronics within their separate environmental rating.
Features:
- Match the complete ordering identity, mounting interface, electrical connections and operating limits
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 107770-03-03 velocity transducer requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 107770-03-03 requires comparing the complete ordering identity, mounting interface, electrical connections and operating limits. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
Select a receiver input compatible with the specified velocity sensitivity, bias and excitation arrangement. Do not substitute a self-generating moving-coil sensor solely because both devices measure velocity. The 21128 housing requires the documented 89477 cable; 84661 is not its approved cable substitute.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 107770-03-03 velocity transducer requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 107770-03-03
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What is the documented identity of 107770-03-03?
This assembled order combines a 330500 sensor with the 21128 housing, a one-half-inch NPT mounting interface and the selected conduit outlet. Confirm the complete approved installation, including the required cable, before treating it as an interchangeable sensor assembly. -
What function does this velocity transducer perform?
It converts vibration at the mounting surface into a velocity signal for the receiving instrument. Correct mechanical coupling and a compatible input are essential; the application must remain within the documented frequency response and environmental limits of the supplied configuration. -
What must be matched when connecting this 107770?
Select a receiver input compatible with the specified velocity sensitivity, bias and excitation arrangement. Do not substitute a self-generating moving-coil sensor solely because both devices measure velocity. The 21128 housing requires the documented 89477 cable; 84661 is not its approved cable substitute. -
Which documented application is relevant to this configuration?
The manufacturer includes structural vibration among the sensing-family applications; select mounting position and response limits for the actual measurement. -
What must the installer check before commissioning?
Use the documented mounting interface and torque where specified. Secure the cable and confirm the input polarity, excitation and operating range before energizing. For high-temperature systems, keep the electronics within their separate environmental rating. -
What is the specified conduit outlet?
1/2-14 NPT with explosion-proof cable gland seal. This value belongs to the documented product or family scope; unresolved ordering fields are not inferred. -
Are all suffixes, revisions and replacements confirmed?
The listed ordering options are supported by the referenced table. Product hardware revisions, discontinuation dates and designated successors require separate manufacturer confirmation; a document revision does not establish a product revision.
